A special synthetic resin membrane (degassing membrane) is used to selectively remove dissolved gasses ; using the charastaristics of the small molecular size of the dissolved gas with high mobility and affinity to the membrane.

Functions, displays:

Power On/Off display : "POWER" LED lights, when the power is supplied

Status monitoring function : "READY" LED lights, when the internalpressure in the vacuum chamber is below a predetermined limit

Pressure monitoring function : "PRES" LED lights, when the internalpressure in the vacuum chamber does not reach a predetermined level within a predetermined time

Leak monitor : "LEAK" LED lights, when the liquid leaks in the apparatus

When ion-exchanged water saturated with air at 25 ̊C is put through at a flow rate of 3 mL/min, no bubble is observed at the outlet of the apparatus. (Measured dissolved oxygen level at the outlet: 2 ppm at flow rate of 3 mL/min)
